Can you use winter tires all year round

[Perfectlap]

this my first winter on dedicated winter tires, Pirelli Snowsports. I mounted them back in October, a bit early by I had a puncture to one of my summer tires.
In April I'll put on the Michelin PS and run them until the fall.

I think up here in the North East using all season tires is useless. They are no damn good in the snow and warm weather performance is crap too.

Like Sammy said hot weather and winter tire durability don't mix. I also have doubts about how good the added stress would be for your CV joints and the drive train itself. I know that some 911 owners were being warned by Porsche about putting too many miles at high RPMs on super soft compounds and the possibility of denying warranty claims for using r comps.
